With this mod, long handed inserters and regular ones behave the exact same. So I feel like I'm cheating in a way, as long handed inserters are still there, and cost more. You'd think they'd be faster than regular ones or something, to be better at long range insertions. Cause, long handed.

If you look at the stats, they actually are faster than the standard inserter.
Inserter:
rotation_speed = 0.014,
LH Inserter:
rotation_speed = 0.02,

If you use Bob's Logistics mod, then that does change all the stats to make the difference more obvious.
